the neat bitumen, an oil refining by-product, has its own inherent weakness under long-time loading at low and high temperatures. these performance limitations of neat bitumen have led researchers to modify its physical andmechanical properties. according to several studies, polymers can be used to modify the properties of bitumen. due to much lower production costs and aiming to reduce environ...

Purpose – The purpose of this paper is to focus on optimization of recycling of concrete from lightweight aggregates containing expanded glass and hard polyurethane (PU) and on the issue of importance of environmental management in constructions, to produce the new combination using rest, construction waste of concrete from lightweight aggregates and hard PU new raw components of concrete from ...

We study how a manufacturer’s recycled content claim decision is impacted by demand for recycled content through environmentally preferable purchasing (EPP) programs and supply uncertainty. We model a manufacturer making a recycled content commitment that can commit to a minimum recycled content that holds for every period (product specific claim), or an average recycled content across periods ...

In the field of construction, sustainable building materials are currently undergoing a process of technological development. This study aims to contribute to understanding the behavior of the fundamental properties of concretes prepared with recycled coarse aggregates that incorporate a polyethylene terephthalate (PET)-based additive in their matrix (produced by synthesis and glycolysis of rec...
